如何将组件置于其他组件之上？ [英] How to put a component on top of others?

问题描述

我有一个 JScrollPanel ，其中包括一个大面板，它自己包含3个内部面板。我想把一个面板（例如）放在一个特殊的地方，以便始终可以看到，我的意思是用户可以滚动到任何想要的地方，但该面板始终位于其他组件的顶部，并且不会移动。我尝试通过 JLayeredPane 来做到这一点，但我做不到。我怎么能这样做？

解决方案

有一个 >。

I have a JScrollPanel that includes a big panel which it's self includes 3 inner panels. i want to put a panel (for example) in a special place so that always could be seen, I mean the user can scroll to anywhere wants but that panel always is in top of the other components and doesn't move. I tried to do that via JLayeredPane but I couldn't. how may I do that?

解决方案

There's a JLayeredPane example here, but OverlayLayout, seen here, may be of interest. It's not included in the conventional gallery.

Also consider this example that paints on the scroll pane's JViewport.
